BACKGROUND

[0002] Along with technological development, smartphones are widely used, and people will cover a phone case in the outside of the smartphone when buying the smartphone. The phone case can protect the smartphone, and decorate the phone to make the phone case more personalized.

[0003] In order to reduce labor costs, phone case customized unmanned vending machines are usually placed in shopping malls or some areas with a high volume of pedestrian flow to achieve unmanned self-service vending. Phone case customized unmanned vending machines can print images and designs provided by users onto a phone case via a printing device to offer personalized services.

[0004] The applicant discovered that: The print head of the printing device is positioned sufficiently close to the rear surface of the phone case to minimize the height difference between the print head and the printing surface of the phone case, thereby achieving clearer printing results. However, the rear surface of the current phone case usually has a protective frame structure for the camera lens, and these frames are fixed. Since the frames protrude from the rear surface of the phone case, the print head of the printing device is prone to colliding with the frames during printing, thereby affecting the printing quality.

SUMMARY

[0005] Based on this, the present application provides a mobile phone case assembly, to overcome the deficiencies in the prior art.

[0006] In independent claim 1, the present application provides a mobile phone case assembly, and defines a mobile phone case assembly of independent claim 1 in some embodiments.

[0007] The present application further defines the mobile phone case assembly in claims 2-14, and defines a mobile phone case customized unmanned vending apparatus in claims 15.

[0008] Compared with the prior art, the detachable lens protection frame of the mobile phone case assembly in the present application is capable of preventing the lens protective frame from interfering with the movement of the printing head of the printing device. By configuring the lens protective frame as detachable, it remains separated from the mobile phone case body and is stored in the storage slot before printing. During printing, since the lens protective frame is not mounted on the mobile phone case body, it avoids the lens protective frame from hindering the printing head of the printing device from approaching the printing surface. The supporting shell is used to support the mobile phone case body, making the mobile phone case body is not prone to deform during transportation. The lens protective frame is stored in the storage slot in the mobile phone case body. This facilitates users fitting the lens protective frame immediately upon receiving the printed mobile phone case body, and it is also convenient for production, packaging and transportation. Once the mobile phone case has been printed, the lens protective frame is removed from the support shell and fitted into the mobile phone lens avoidance hole of the mobile phone case to body form a complete mobile phone case.

[0009] In addition, the mobile phone case assembly is not limited to being applied to the mobile phone case customized unmanned vending apparatus. They are also used in manually customized mobile phone case assembly, such as custom mobile phone cases printed by desktop UV printers, and custom mobile phone cases by hand-cut, etc.

[0010] The mobile phone case customized unmanned vending apparatus is designed with the rational layout of various structure of the mobile phone case customized unmanned vending machine. This makes the overall structure simple, the printing precise and the effect good, enabling the automatic printing and selling of the mobile phone cases.

[0011] For better understanding and implementation, the present application is described in detail below in conjunction with drawings.

A first embodiment

[0018] Referring to FIG. 1 and 2, a mobile phone case assembly is provided in this embodiment of the present application, comprising:
Mobile phone case body 101, which is configured with a receiving slot 1011 for holding a phone.

[0019] Printing section 1019, which is positioned on one side of the mobile phone case body 101 opposite the receiving slot 1011. A printing surface 1020 with a predetermined color is formed on the printing section 1019. The printing surface 1020 is aligned with or protrudes beyond the side of the mobile phone case body 101 opposite the receiving slot 1011. The printing surface is a single complete flat plane or composed of multiple flat planes joined together. For example, it consists of several independent printing surfaces arranged in a stepped configuration at different heights on the side of the mobile phone case body 101 opposite the receiving slot 1011, or each independent printing surface is separately arranged on the same horizontal plane.

[0020] The printing surface 1020 of the printing section 1019 is used for adhering printed ink. The printing section 1019 is integrally injection molded with the mobile phone case body 101, or assembled with the mobile phone case body 101 using other suitable methods. To facilitate the distinction between the printing section 1019 and the mobile phone case body 101, the edges of the printing surface 1020 form a distinct boundary with the mobile phone case body 101. This facilitates the printing device in recognizing the contour of the printing surface 1020, thereby enabling efficient printing.

[0021] During printing, the receiving slot 1011 of the mobile phone case body 101 is facing downward and the printing section 1019 facing upward. The printing surface 1020 is positioned at the highest point relative to the mobile phone case assembly. This allows the printing head of the printing device to achieve the optimal distance from the printing surface 1020 for printing without interference from other structures of the mobile phone case body 101, resulting in a clearer print quality.

[0022] The predetermined color is typically white because the printing device usually needs to spray a layer of ink, such as white ink, onto the printing position before printing the pattern. This ensures that the corresponding ink for the subsequent printed pattern adheres properly. The printing surface 1020 is preset to be white, which eliminates the need for the printing device to apply white ink thus saving printing time. Furthermore, when the printing device is not used for a period of time, the white ink often clogs the nozzles of the printing device, leading to the need for maintenance, eliminating the application of white ink can also reduce the frequency of maintenance and prevent the clogging of the printing device's nozzle.

[0023] Additionally, to meet personalized demands, the mobile phone case body 101 usually comes into different colors, while the printing surface 1020 adopts a distinct preset color, which also facilitates the distinction from the color of the mobile phone case body 101, and make it convenient for the printing device to accurately identify the printing surface 1020.However, depending on the actual situation, the preset color is also selected as other appropriate colors as needed, not limited to this example.

[0024] Referring to FIG. 3 and FIG.4, the receiving slot 1011 is provided with a mobile phone lens avoidance hole 1012, which extends to the side of the mobile phone case body 101 opposite the receiving slot 1011. After the mobile phone is placed into the receiving slot 1011, the mobile phone lens extent into the mobile phone lens avoidance hole 1012, or be positioned relative to the mobile phone lens avoidance hole 1012. The mobile phone case assembly further includes a lens protective frame 103, which is positioned at the mobile phone lens avoidance hole 1012 and detachably mounted to the mobile phone case body 101; or, the mobile phone case assembly further includes a plurality of lens protective frames 103 with different structures, any one of the lens protective frames 103 is positioned at the mobile phone lens avoidance hole 1012 and detachably mounted to the mobile phone case body 101 to form a flat printing surface on the side of the mobile phone case body 101 opposite the receiving slot 1011. When the lens protective frames 103 is not assembled with the mobile phone lens avoidance hole 1012, the printing surface is usually the highest point on the side of the mobile phone case body 101 opposite the mounting slot 1011 to allow the printing head of the printing device is able to positioned very close to the printing surface during printing, thereby enhancing printing precision and quality.

[0025] The lens protective frame 103 is designed to be detachable from the mobile phone case body 101. The purpose is to prevent the lens protective frame 103 from interfering with the printing head of the printing device from approaching the printing surface 1020. Since phones lenses usually protrude from the rear side of the phones, the lens of the phone pass through the mobile phone lens avoidance hole 1012. Consequently, the lens protective frame 103 requires sufficient height. This results in the lens protective frame 103 being positioned higher than the printing surface 1020 when the phone case body 101 is placed with the receiving slot 1011 facing downward. To avoid the lens protective frame 103, the printing head of the printing device increases the height, which results an excessive distance between the printing surface 1020 and the printing head of the printing device. By making the lens protective frame 103 to be removable, the mobile phone case assembly and the lens protective frame 103 are pre-stored in the mobile phone case customized unmanned vending machine. Before printing, the lens protective frame 103 is detached from the mobile phone case body 101. During printing, since the lens protective frame 103 is not mounted on the mobile phone case body 101, the lens protective frame 103 avoids from hindering the printing head of the printing device from approaching the printing surface 1020. After printing is complete, the lens protective frame 103 is installed onto the mobile phone case body 101.

[0026] In cases that the mobile phone case assembly includes a plurality of lens protective frames 103, users select the appropriate lens protective frame 103 to install on the mobile phone case body 101 according to their needs to meet personalized requirements.

[0027] In some embodiments, when the lens protective frame 103 is mounted on the mobile phone case body 101, the lens protective frame 103 protrudes from the side of the mobile phone case body 101 opposite the receiving slot 1011, and the height of the lens protective frame 103 relative to the side of the mobile phone case body 101 opposite the receiving slot 1011 is greater than the height of the lens protective frame 103 relative to the printing surface 1020. When the mobile phone case body 101 is placed with the receiving slot 1011 facing downward, the top of the lens protective frame 103 is higher than the height of the printing surface 1020. Therefore, before printing, the lens protective frame 103 is separated from the mobile phone case body 101 to prevent interference with the printing process. After the lens protective frame 103is installed onto the mobile phone case body 101, the lens protective frame 103 also provides enough height to accommodate the lens of the mobile phone, which is conducive to protecting the lens of the mobile phone.

[0028] Referring to FIG.5 to FIG.8, in some embodiments, the lens protective frame 103 is a first protective frame 1032, a second protective frame 1033, a third protective frame 1034, or a fourth protective frame 1035. When the mobile phone case assembly includes a lens protective frame 103, the lens protective frame 103 is one of the first protective frame 1032, the second protective frame 1033, the third protective frame 1034, or the fourth protective frame 1035. When the mobile phone case assembly includes a plurality of lens protection frames 103, a plurality of the lens protective frames 103 are a combination of the first protective frame 1032, the second protective frame 1033, the third protective frame 1034, or the fourth protection frame 1035.For example, the mobile phone case assembly includes two lens protective frames 103, one of which is the first protective frame 1032, and the other is the second protective frame 1033. The configuration of multiple protective frames is conducive to meeting the personalized needs of the users.

[0029] A plurality of light through holes 1321 are provided on the first protective frame 1032, and a light transmission lens 1322 is installed in the light through hole 1321 to enhance the protective properties for the mobile phone lens and improve the sealing properties of the light through hole 1321. Or in other embodiments, the light transmission lens 1322 are omitted in the light through holes 1321, so that the light through holes 1321 remain unobstructed, facilitating the avoidance of structures or accessories on the mobile phone lens. Alternatively, other suitable light transmitting structures or functional structures are able to set inside the light through holes 1321. In the present embodiment, the light transmission lens 1322 is placed inside the light through hole 1321. When the first protective frame 1032 is detachably mounted to the mobile phone case body 101, the first protective frame 1032 covers the mobile phone lens avoidance hole 1012, and the light through hole 1321 communicates with the mobile phone lens avoidance hole 1012. The first protective frame 1032 enhances protection for the mobile phone lens by covering the mobile phone lens avoidance hole 1012. The light through hole 1321 is positioned to correspond with the mobile phone lens, while the lens prevents dust and other impurities from entering through the light through hole 1321. When a plurality of lenses is installed on the mobile phone, a plurality of light through holes 1321 is configured on the first protective frame 1032, which are arranged in correspondence with the lenses. The communication between the light through holes 1321 and the mobile phone lens avoidance hole 1012 means that light is able to pass through the light through holes 1321 into the mobile phone lens avoidance hole 1012.

[0030] A first avoidance frame opening 1331 is provided on the second protective frame 1033. When the second protective frame 1033 is detachably mounted to the mobile phone case body 101, the second protective frame 1033 surrounds the mobile phone lens avoidance hole 1012, with the first avoidance frame opening 1331 communicating with the mobile phone lens avoidance hole 1012. Due to some users having installed decorations or functional components on the lenses of the mobile phones, in order to prevent the second protective frame 1033 from interfering with the decorations, the second protective frame 1033 is placed around the lens of the mobile phone, providing protection for the sides of the mobile phone lens. And the decorations or the functional components are able to extend into the first avoidance frame opening 1331, preventing interference between the second protective frame 1033 and the decorations or the functional components.

[0031] A second avoidance frame opening 1341 and a protective cover 1342 are provided on the third protective frame 1033.The protective cover 1342 is movably coupled to the third protective frame 1034 and is able to move relative to the third protective frame 1034 to a position closing the second avoidance frame opening 1341 or to a position opening the second avoidance frame opening 1341. When the third protective frame 1035 is detachably mounted to the mobile phone case body 101, the second protective frame 1033 surrounds the mobile phone lens avoidance hole 1012, with the second avoidance frame opening 1341 communicating with the mobile phone lens avoidance hole 1012. By opening or closing the protective cover 1342, the user opens the protective cover 1342 when using the mobile phone lens and close the protective cover 1342 when not using the mobile phone lens, thereby providing effective protection for the mobile phone lens. The protective cover 1342 is slidably or rotatably mounted to the third protective frame 1034. For example, the protective cover 1342 is able to rotate relative to the third protective frame 1034 via a pivot shaft, or alternatively, a slide groove is provided on the third protective frame 1034, and the protective cover 1342 slides in the slide groove.

[0032] A bracket 1351 is provided on the fourth protective frame 1035. The bracket 1351 is movably mounted to the fourth protective frame 1035 and is able to move relative to the fourth protective frame 1035 to a folded position and an unfolded position. When the fourth protective frame 1035 is detachably mounted to the mobile phone case body 101, the fourth protective frame 1035 is positioned at the mobile phone lens avoidance hole 1012. When the bracket 1351 is in the unfolded position, the bracket 1351 extends to the outside of the mobile phone case body 101 on the side opposite to the receiving slot 1011. The bracket 1351 provides support for the mobile phone case body 101 as a phone stand. When the mobile phone needs to be placed upright or titled on the table, the bracket 1351 is moved to the unfold position. The mobile phone case body 101 is supported by the bracket 1351, thereby maintaining the position of the mobile phone. When the bracket 1351 is in the folded position, the bracket 1351 is positioned close to the fourth protective frame 1035 or the side of the mobile phone case body 101 opposite the receiving slot 1011, or the bracket 1351 maintains a minimal clearance from the fourth protective frame 1035 or the side of the mobile phone case body 101 opposite the receiving slot 1011, preventing the bracket 1351 from interfering with the user's grip on the mobile phone case body 101. In this embodiment, the bracket 1351 is rotatably mounted to the fourth protective frame 1035, using a similar mounting method to the protective cover 1342 on the third protective frame 1034. But, depending on the specific structure of the bracket 1351, other means of movement are also used, not limited to this example. The structure of the fourth protective frame 1035 is able to be achieved by adding the bracket 1351 on the first protective frame 1032 or the second protective frame 1033.

[0033] However, the structure of the lens protective frame 103 is not limited to the structure of the first protective frame 1032, the second protective frame 1033, the third protective frame 1034, and the fourth protective frame 1035.

When the supporting shell 102 is positioned within the receiving slot 1011, the first avoidance recess 1024 communicates with the receiving slot 1011. In these embodiments, the first avoidance recess 1024 and the receiving groove 1011 of the mobile phone case body define a space for the user's fingers to insert together. In some embodiments, at least two of the first avoidance recesses 1024 are arranged on opposite sides of the supporting shell 102, and the two first avoidance recesses 1024 are symmetrically arranged relative to the supporting shell 102. Users insert two fingers into the first avoidance recesses 1024 on both sides of the supporting shell 102, grasping both sides of the supporting shell 102 to make easy to remove the supporting shell 102.

[0039] In some embodiments, the first limiting flange 1022 is integrally formed with the mobile phone case body 101, and the supporting shell 102 is formed by thermoforming a rigid plastic film into a single piece. The second limiting flange 1023 and the first avoidance recess 1024 are also integrally formed with the supporting shell 102.

[0040] In some embodiments, a limiting protrusion 1025 extending inward toward the interior of the storage slot 1021 is provided from the top edge of the storage slot 1021 of the supporting shell 102. The lens protective frame 103 is detachably stored in the storage slot 1021 by the limiting protrusion 1025. Referring to FIG.13 and FIG.14 the limiting protrusion 1025 projects inward from the top edge of the storage slot 1021. The supporting shell 102 is made from elastic materials. When the lens protective frame 103 is inserted, the limiting protrusions 1025 are pushed apart by the lens protective frame 103, allowing the lens protective frame to place into the storage slot 1021. Subsequently, the limiting protrusions 1025 recovers to its original position under the effect of elastic materials, securely retaining the lens protective frame 103 within the storage slot 1021. This prevents the lens protective frame from easily falling out during handling or similar actions. When removing the lens protective frame 103, grasp the lens protective frame 103 and pull it out forcefully from the storage slot 1021.In some embodiments, at least two of the limiting protrusions 1025 are positioned at opposite sides of the storage slot 1021, with an arcuate transition surface 1026 formed between the limiting protrusions 1025 and the inner surface of the storage slot 1021.

[0041] In some embodiments, the supporting shell 102 is formed by thermoforming a rigid plastic film. The limiting protrusion 1025 is also integrally molded with the supporting shell 102.

[0042] In some embodiments, the supporting shell 102 further includes a second avoidance recess 1027 positioned at the edge of the storage slot 1021 for finger insertion. The second avoidance recess 1027 communicates with the storage slot 1021, allowing the user to insert a finger to conveniently remove the lens protective frame 103 from the storage slot 1021. After printing is completed on the printing surface of the mobile phone case body 101, the user removes the lens protective frame 103 from the storage slot 1021 and install it onto the mobile phone lens avoidance hole 1012 of the mobile phone case body 101 to protect the lens assembly of the mobile phone when the mobile phone is placed into the storage slot 1011 of the mobile phone case body 101. When removing the protective frame 103 from the storage slot 1021, the user inserts their finger into the second avoidance recess 1027, positioning the finger against the edge of the lens protective frame 103 to remove the protective frame 103. In the other embodiments, at least two of the second avoidance recess 1027 are positioned on opposite sides of the storage slot 1021, with the two second avoidance recess 1027 symmetrically arranged relative to the storage slot 1021. This configuration allows for better gripping of the two edges of the lens protective frame 103 with two fingers, enabling the lens protective frame 103 to be removed from the storage slot 1021 by applying force.

[0043] In some embodiments, the storage slot 1021is rectangular. At least two rectangular storage slots 1021 are arranged sequentially along the lengthwise direction of the supporting shell 102, and the storage slots 1021 are inclined relative to the supporting shell 102. When the supporting shell 102 is positioned in the receiving slot 1011, at least one corner of at least one of the storage slots 1021 communicates with the receiving slot 1011. By tilting the rectangular storage slot 1021 relative to the supporting shell 102, the volume of the storage slot 1021 is increased to accommodate larger lens protection frames 103. This configuration offers particular advantages for smartphones with larger lens modules. This implementation method is beneficial for the use of larger lens modules in the mobile phones.

[0044] Referring to FIG.11, in some embodiments, the lens protective frame 103 is provided with a snap groove 1031, and a clamping section 1013 is provided in the mobile phone lens avoidance hole 1012 extending circumferentially along the mobile phone lens avoidance hole 1012.

The printing section 1019 is bonded in the second locating groove 1016, or the printing section 1019 is snap-fitted into the second locating groove 1016. In the present embodiment, the printing section 1019 adheres to the second locating groove 1016 via a colloidal layer, achieving stable fixation of the printing section 1019, and the second location slot 1016 prevents the printing section 1019 from sliding, thereby enhancing bonding stability. In the other embodiments, the printing section 1019 is installed in the second locating slot 1016 via a snap-fit method. For example, the printing section 1019 is interference-fit with the second locating groove 1016, or the inner side of the second locating groove 1016 is provided with a snap-fit groove, with the printing section 1019 snap-fitting into the snap-fit groove, thereby facilitating the installation and replacement of the printing section 1019. However, the installation method of the printing section 1019 is not limited to these embodiments. In the other embodiments, the skilled in the art select other suitable installation methods based on this application. For example, the printing section 1019 is integrally injection molded with the mobile phone case body 101.

[0048] In some embodiments, a mounting slot 1017 is provided on the side of the mobile phone case body 101 opposite the storage slot 1011. A magnetic part 1018 is positioned in the mounting slot 1017, and the printing section 1019 covers both the mounting slot 1017 and the magnetic part 1018.The Magnetic part 1018 is magnet, iron pieces, etc. When wireless charging is required, the magnetic part 1018 facilitates the magnetic adhesion connection between the mobile phone case body 101 and the charging device. Furthermore, during storage and transportation of the mobile phone case body 101, magnetic attraction enables grasping and handling of the mobile phone case body 101. In the present embodiment, the mounting slot 1017 is provided in the second locating slot 1016.

[0049] In some embodiments, the storage slot 1011 is provided with an Identifying section 1014 corresponding to the position of the magnetic part 1018. The Identifying section 1014 indicates the position of the magnetic part 1018, facilitating users to perform appropriate operations.

[0081] The printing head unit 510 and the position detection unit 530 are respectively arranged on two sides of the supporting beam 41, the supporting beam 41 is able to block consumable materials, so that the consumable materials sprayed out of the printing head unit 510 are prevented from being adhered to the position detection unit 530 to effectively prevent the position detection unit 530 from becoming contaminated by consumables. It also avoids the need for frequent replacement or cleaning of the position detection unit 530, thereby significantly reducing maintenance frequency.

[0082] Referring to FIG.23 to FIG.25, in some embodiments, the specific structure of the position detecting unit 530 is appropriately designed according to practical needs. For example, the position detecting unit 530 is an electro-optical distance measuring sensor assembly or an infrared distance measuring sensor assembly, etc. In the present embodiment, the position detecting unit 530 includes a grating sensor 531 and a grating strip 532, the grating sensor 531 senses the grating strip 532, the grating sensor 531 and the grating strip 532 are both disposed on one side of the support beam 41 opposite the printing head unit 510, the grating sensor 531 is connected with the printing head unit 510. Benefiting from the blocking effect of the support beam 41, it prevents consumable materials sprayed by the printing head unit 510 from adhering to the grating sensor 531 or the grating strip 532, particularly to prevent the grating strip 532 from being polluted by the consumable materials. Because the grating strip 532 is long in length and limited by the sensing distance of the grating strip 532 and the grating sensor 531, the surface of the grating strip 532 needs to be kept clean. However, in the other embodiments, the position detection unit 530 adopts other suitable structures and is not limited to the grating sensor 531 and grating strip 532.

[0083] In some embodiments, the side of the support beam 41 opposite the printing head unit 510 is provided with two grating mounting holders 412, and the grating strip 532 is mounted on the two grating mounting holders 412 with the grating sensor 531 located between the two grating mounting holders 412.

[0084] In some embodiments, a first limiting section 413 is provided on the grating mounting holder 412, two second limiting sections 511 are provided on the printing head unit 510, the two second limiting sections 511 are positioned on two sides of the grating sensor 531 respectively, the two second limiting sections 511 are positioned between the two first limiting section 413, the first limiting section 413 limits the corresponding second limiting section 511. When the grating sensor 531 moves to a limiting position, the first limiting section 413 and the second limiting section 511 abut against each other to limit the position of the grating sensor 531 relative to the grating strips 532.

[0085] Referring to FIG.26 and FIG.27, in some embodiments, the printing mechanism 50 further includes a protective cover 540, the protective cover 540 surrounds to form a printing space 541. The printing space 541 is positioned on the side of the support beam 41 facing the printing head unit 510 and below the printing head unit 510, and the protective cover 540 is used for blocking consumable materials sprayed from the printing head unit 510, so as to further effectively prevent the consumable materials from splashing in the environment, bypassing the support beam 41 and adhering to the grating sensor 531 or the grating strip 532.The printing position is located in the printing space 541, and the loading position is located outside the printing space 541 or inside the printing space 541.

[0086] In some embodiments, portions of the protective cover 540 are disposed on the side of the support beam 41 opposite the printing head unit 510 and below the grating sensor 531 and grating strip 532. Since the printing space 541 is located on the side of the support beam 41 facing the printing head unit 510 and below the printing head unit 510, the splattered consumable materials primarily disperse from beneath the support beam 41. By using the protective cover 540 to shield the bottom of the grating sensor 531 and the grating bars 532, it cooperates with the supporting beam 41 to further prevent the consumable materials from coming into contact with the grating sensor 531 and the grating bars 532.

[0087] In some embodiments, both the head guide rail 411 and the printing head drive unit 520 are disposed on the side of the support beam 41 facing the printing head unit 510, thereby providing sufficient space for the layout of the grating sensor 531 and the grating strip 532.

In the present embodiment, the grating sensor 531 and the second limiting section 511 are disposed at the bottom of the extension section 512, and the grating strip 532 is disposed at the side of the support beam 41 opposite the printing head unit 510.

[0089] In addition, due to the blocking of the extension section 512, consumable materials are further prevented from contacting the grating sensor 531 and the grating strip 532. In the present embodiment, the extension section 512 is located above the grating sensor 531 and the grating strip 532, and the part of the protective cover 540 is located below the grating sensor 531 and the grating strip 532, and the support beam 41 is located at one side of the grating sensor 531 and the grating strip 532 facing the printing head unit 510, so that consumable materials are blocked in three directions, and the consumable materials are effectively prevented from contacting the grating sensor 531 and the grating strip 532.

[0090] In some embodiments, the extension section 512 is connected with a towing chain 513, the towing chain 513 is located on the side of the support beam 41 opposite the printing head unit 510, and the d towing chain 513 is used for protecting pipes and wires such as cables, oil pipes, air pipes, etc. Since the towing chain 513 is disposed on the side of the support beam 41 opposite the printing head unit 510, consumable materials are prevented from adhering to the towing chain 513 and the pipes or wires positioned on the towing chain 513, so that the towing chain 513 operates smoothly while protecting the pipes and wires.

[0091] The specific structure of the head guide rail 411 is appropriately designed according to practical needs. For example, the head guide rail 411 is a convex rail, and the printing head unit 510 is slidingly matched with the convex rail through a sliding block, which is not limited to this example.

[0100] In some embodiments, the sides of any two adjacent positioning parts 622 for positioning the mobile phone housing 90 are perpendicular to each other. When the mobile phone case 90 is inclined relative to the side of the positioning part 622 for positioning the mobile phone case 90, with the side surface of the positioning part 622 abutting the mobile phone case 90, pushing the mobile phone case 90 into the shaping position 611 drives the mobile phone case 90 to gradually align with the side edge corresponding to the shaping position 611, so that the mobile phone case 90 is accurately positioned.

[0107] In some alternative embodiments, the mobile phone case shaping seat 610 is provided with a mobile phone case detection unit 614, where the mobile phone case detection unit 614 faces the shaping position 611 and is connected to a positioning drive unit 621 via a signal. The mobile phone case detection unit 614 is configured to detect whether the mobile phone case 90 is placed at the shaping position 611.

[0108] Referring to FIG.34 and FIG.35, in some embodiments, the height adjustment mechanism 70 includes:

[0109] A lifting drive unit 710, which is connected to the mobile phone case shaping jig 610 with a driving manner and is used for driving the mobile phone case shaping seat 610 of the mobile phone case shaping jig 60 to lift.

[0110] A height detection unit 720, which is used for detecting whether the mobile phone case 90 reaches a preset height. The height detection unit 720 is disposed at one side of the mobile phone case shaping jig 60 and is connected to the lifting drive unit 710 via a signal. The height of the mobile phone case shaping seat 610 is adjusted through the lifting drive unit 710 to adjust the height of the mobile phone shell 90. Whether the mobile phone shell 90 reaches the preset height is judged through the height detection unit 720. After the lifting drive unit 710 drives the mobile phone case shaping seat 610 to lift so that the mobile phone case 90 reaches the preset height, the mobile phone case 90 is printed by the printer mechanism, the height of the mobile phone shell shaping seat 610 is adjusted through the lifting drive unit 710 so as to adapt to thickness differences of different mobile phone cases 90, the effect of printing is prevented from being influenced by thickness differences of different mobile phone cases 90, the whole structure is simpler, and the cost is lower.

[0111] It should be noted that, when the mobile phone case 90 is at the preset height, the distance between the top surface of the mobile phone case 90 and the printing mechanism 50 enables the printing mechanism 50 to perform effective printing, and the top surface of the mobile phone case 90 is not far away from or near to the printing mechanism 50 so as to affect the printing effect, and the printing mechanism 50 does not collide with the mobile phone case 90.

[0112] In some embodiments, the mobile phone case printing device 30 further includes a conveying mechanism 80. The conveying mechanism 80 is disposed on the supporter 40 and is connected to the height adjustment mechanism 70 in a driving manner, and drives the height adjustment mechanism 70 to move to the loading position and the printing position relative to the printing mechanism 50.

[0113] Through the conveying mechanism 80 moves the high adjustment mechanism 70 as a whole to the loading position keeping away from the printing mechanism 50, facilitating the placement of the mobile phone case 90 onto the mobile phone case shaping seat 610. This prevents the printing mechanism 50 from obstructing the placement process of the mobile phone case 90. After the mobile phone 90 is placed, the conveying mechanism 80 carries the mobile phone case 90 to the printing position beneath the printing mechanism 50, enabling printing on the mobile phone case 90. In the present embodiment, the printing position and the loading position are sequentially arranged in the direction close to the mobile phone case storage and conveying mechanism 20. This facilitates the rapid placement of the mobile phone case 90 onto the mobile phone case shaping jig 60 by the mobile phone case storage and conveying mechanism 20, thereby shortening the movement path of the mobile phone cases 90.

[0114] When the conveying mechanism 80 drives the height adjustment mechanism 70 to move from the loading position to the printing position, the height of the mobile phone case 90 is adjusted. When the height detection unit 720 detects that the mobile phone case 90 at the preset height, the lifting drive unit 710 drives the mobile phone case shaping jig 60 to slowly descend until the height detection unit 720 does not detect the mobile phone case 90 is at the preset height, the mobile phone case shaping jig 60 stops descending immediately, so that the top surface of the mobile phone case 90 is just at the preset height. When the height detection unit 720 does not detect the mobile phone case 90 at the preset height, the lifting drive unit 710 drives the mobile phone case shaping jig 60 to ascend until the height detection unit 720 detects the mobile phone casing 90 is at the preset height, and then the lifting drive unit 710 drives the mobile phone case shaping jig 60 to slowly descend until the height detection unit 720 just does not detect the mobile phone case 90 is at the preset height, the mobile phone case shaping jig 60 stops descending immediately, so that the top surface of the mobile phone case 90 is just at the preset height.

[0115] The specific manner in which the height detection unit 720 determines whether the height of the mobile phone case 90 reaches the preset height is appropriately designed according to practical needs. For example, in some embodiments, the height detection unit 720 includes a light emitter 721 and a light receiver 722. The light emitter 721 and the light receiver 722 are disposed on two sides of the mobile phone case shaping jig 60. The light emitter 721 is selected from different types, such as an infrared light emitter 721, a visible light emitter 721, and so on. In the present embodiment, the light emitter 721 is a laser transmitter, the light receiver 722 is a laser receiver, and the laser transmitter and the laser receiver are arranged at the preset height and are positioned between the loading position and the printing position, and are used for detecting whether the mobile phone case 90 is at the preset height in real time. The laser receiver judges whether the mobile phone case 90 is or is not by detecting laser emitted by the laser transmitter, and further judges whether the mobile phone case 90 exceeds the preset height. When the laser receiver does not receive the laser emitted by the laser transmitter, it indicates that the mobile phone case 90 is detected, the mobile phone case 90 exceeds the preset height, the laser transmitter sends a signal to the lifting drive unit 710, the lifting drive unit 710 drives the mobile phone case shaping jig 60 to slowly descend until the laser receiver receives laser emitted by the laser transmitter, the lifting drive unit 710 stops descending immediately. At this moment, the mobile phone case 90 is not detected, meaning the mobile phone case 90 is precisely at the preset height. When the laser receiver receives the laser emitted by the laser transmitter, it indicates that the mobile phone case 90 is not detected, the mobile phone case 90 is lower than the preset height, the laser transmitter sends a signal to the lifting drive unit 710, the lifting drive unit 710 drives the mobile phone case shaping jig 60 to ascend until the laser receiver no longer receives laser emitted. At this moment, the mobile phone case 90 exceeds the preset height, the laser transmitter sends a signal to the lifting drive unit 710, the lifting drive unit 710 drives the mobile phone case shaping jig 60 to slowly descend until the laser receiver receives laser emitted by the laser transmitter. That is, when the mobile phone case 90 is not detected, the lifting drive unit 710 immediately stops descending immediately. At this moment, the mobile phone case 90 is precisely at the preset height. In some embodiments, the conveying mechanism 80 and the height adjustment mechanism 70 are operate simultaneously. That is, during the process where the conveying mechanism 80 moves the height adjustment mechanism 70 from the loading position to the printing position, the height adjustment mechanism 70 simultaneously adjusts the height of the mobile phone case 90, thereby improving work efficiency.

[0116] Or in the other embodiments, the height detection unit 720 includes a distance sensor disposed above the mobile phone shaping seat and facing the top of the mobile phone shaping seat. The distance sensor faces the mobile phone case 90 on the mobile phone case shaping jig 60, and determines whether the mobile phone case 90 reaches the preset height correspondingly by detecting the distance between the mobile phone case 90 and the distance sensor. The distance sensor employs different detection modes, such as a proximity switch, an infrared distance measurement sensor, etc., and is not limited to this example.

[0117] Or in the other embodiments, the height detection unit 720 includes a thickness measuring sensor. The thickness measuring sensor is disposed on one side of the mobile phone case shaping jig 60, and detects the thickness of the mobile phone case 90. Since the area to be printed of the mobile phone case 90 is usually located at the top of the mobile phone case 90, subtracting the thickness of the mobile phone case 90 from the preset height is able to obtain the height required to be raised by the mobile phone case shaping jig 60, so that the mobile phone case shaping jig 60 is raised until the mobile phone case 90 reaches the preset height.

[0118] Or in the other embodiments, the height detection unit 720 includes a contact sensor. Determine whether the mobile phone case has reached the preset height by determining whether the mobile phone case is in contact with the contact sensor at the preset height.

[0119] Or in the other embodiments, the height detection unit 720 includes a mobile phone case height calculating unit connected to the lifting drive unit 710 via a signal. The height of the mobile phone case shaping seat 610 is driven by the lifting drive unit 710 and the current height of the mobile phone case shaping seat 610 are calculated in real time. For example, when the lifting drive unit 710 uses a motor as power, the current height of the mobile phone case shaping seat 610 is determined in real time through operation data of the motor. Since the size (length, width and thickness)of the mobile phone case 90 is able to be obtained and stored in advance, after the user selects the mobile phone case 90 with the corresponding model, the mobile phone case storage and conveying mechanism 20 carries the mobile phone case 90, and the mobile phone case height calculating unit receives the thickness information of the mobile phone case 90 selected by the user, and then based on the thickness of the mobile phone case 90 and the current height of the mobile phone case shaping seat 610, the current height of the mobile phone case 90 is measured in real time, and the lifting drive unit 710 adjusts the height of the mobile phone case shaping seat 610 based on the current height of the mobile phone case 90, so that the mobile phone case 90 reaches the preset height. In some embodiments, the mobile phone case height calculating unit employs a processor, an arithmetic circuit, or the like for realizing the calculating function.

[0120] Referring to FIG.36 and FIG.37, the specific structure of the lifting drive unit 710 is appropriately designed according to practical needs. For example, in some embodiments, the lifting drive unit 710 includes a base 711, a lifting power motor 712, a lifting transmission unit 713 and a plurality of lifting lead screws 714. The plurality of lifting screws 714 are disposed on the base 711 and are connected to the mobile phone case shaping seat 610 in a driving manner, the lifting power motor 712 is connected to the height detection unit 720 via a signal. The lifting power motor 712 is connected to the plurality of lifting lead screws 714 through the lifting transmission unit 713.
